BACKGROUND ART

According to the prior art, some of the lighters are disposable. Some are of electronic igniters. Some are windproof.

The problem common to all these ideas was that, none of them is a disposable electronic windproof with Children Resistance function.

There have been proposal for design which has a flint type igniter, i.e., in China patent No. 96247387.1, titled Disposable Windproof Lighter, it proposes a windproof lighter with flint type igniter. But this type of lighter has already rubbed the flint to generate sparks before opening the gas outlet valve, therefore its successful rate of lighting up fire is comparatively low.

SUMMARY OF THE INVENTION

It is therefore an object of this invention to provide a lighter using piezoelectric igniter to generate electric sparks to light up the lighter. It will open the gas outlet valve to release liquefied gas into the combustion chamber of the combustion assembly to be atomized and mixed with air before pressing down the igniter cap to enough low level to touch off the igniter device, which will increase the successful rate of lighting up fire.

The present invention in one embodiment provides a lighter comprising gas tank, gas outlet assembly, seesaw, ignition device, igniter cap etc, wherein the lighter also includes combustion assembly and a copper ring with re-burning component located on top of the combustion assembly, the said ignition device is a piezoelectric igniter, the said gas tank is without gas input assembly. These form up the main parts of a disposable electronic windproof lighter.

The present invention in another embodiment provides an electronic igniter for the lighter wherein the springs inside of the said piezoelectric igniter are strengthened springs. When press them downward for 5 mm, the total resistant force is not less than 4.3 kgs. It's hard for children below 3-years-old to operate such a lighter. This piezoelectric igniter 4 is an electronic igniter with Children Resistance function.

According to this invention, when pull down the cover head, the arm-like structure will press down the igniter cap to firstly start-up the seesaw and then touch off the ignition device. The seesaw will open the valve on the gas outlet assembly to release liquefied gas into combustion chamber of the combustion assembly to be atomized and mixed with air. When the igniter cap is being lowered down to enough level, it will touch off the ignition device to generate electric sparks into the combustion chamber via the ignition wire to light up the mixed air inside of the combustion chamber. To strengthen the fire force, the re-burning component on the copper ring after being heated by flame will light up the mixed air that has not been fully burned. The speed of jet flame is bigger than the speed of the wind outside, therefore it will bring the function of windproof. Comparing with common disposable lighters, the disposable electronic windproof lighter has windproof function besides of its higher successful rate of lighting up fire, which provides more convenience especially when being used in winter or outdoor. This invention helps to improve people's life quality from one point.

These form up the main parts of a disposable electronic windproof lighter. The springs 9 inside of the said piezoelectric igniter 4 are strengthened springs. When press them downward for 5 mm, the total resistant force is not less than 4.3 kgs. It's hard for children below 3-years-old to operate such a lighter. Therefore this piezoelectric igniter 4 is an electronic igniter with Children Resistance function. There is an arm-like structure 11 on the cover head 10. When pull down the cover head 10, the arm-like structure 11 will press down the igniter cap 5 to firstly start-up the seesaw 3 and then touch off the ignition device 4. The seesaw 3 will open the valve on the gas outlet assembly 2 to release liquefied gas into combustion chamber 13 of the combustion assembly 6 to be atomized and mixed with air. When the igniter cap 5 is being lowered down to enough level, it will touch off the ignition device 4 to generate electric sparks into the combustion chamber via the ignition wire 12 to light up the mixed air inside of the combustion chamber. To strengthen the fire force, the re-burning component on the copper ring 7 after being heated by flame will light up the mixed air that has not been fully burned. The speed of jet flame is bigger than the speed of the wind outside, therefore it will bring the function of windproof. When leave go of the head cover 10, the springs inside of the ignition device 4 will automatically reposition the head cover 10 into its original location. The lighter may waive the usage of casing and let the gas tank 1 directly to be naked as the lighter body. The said gas tank 1 is made of transparent or semi-transparent materials, which provides convenience for the user to observe the volume of the liquefied gas left in the gas tank 1. It's another option to make the gas tank 1 with non-transparent materials.

FIG. 4 shows the best mode for carrying out the present invention which includes a casing 15 for the lighter to increase its safety. This will require a fastening screw 16 to fix the casing 15 together with the gas tank 1. The casing 15 is made of plastic or metal materials. There is a knob 14 being added onto the gas outlet assembly 2 that can be revolved around by hand to adjust the volume of outgoing gas. There is a viewing window 18 in the shape of round or any other form near the combustion assembly 6 on the middle bracket 17. It's beautiful and helps heat dissemination of the lighter body. When the gas tank 1 is made of transparent materials while the casing 15 is made of non-transparent plastic or metal materials, a vertical observing window 19 in the shape of a strip should be opened on the casing 15, which provides convenience for the user to observe the volume of the liquefied gas left in the gas tank 1. In this circumstance, the invention has a better effect.
